my auntie mentioned to me the other day to boil this drink to help nourish our lung. apparently it is also good for heavy smokers, body heatiness and bad breath. more info can be read from this site.
this is the sweet version of watercress soup. my beloved grandma made this for us, upon request. she used 2kg of watercress (cleaned thoroughly) + 15 pcs of honey dates, boiled for 4 hours using charcoal fire.
hubs and i love it so much that we finish drinking this big pot of concoction in 1 day!
